Ill-met by moonlight for dinosaur prey

Night would have been a scary time when dinosaurs roamed the Earth, scientists believe.

New evidence challenges the theory that vicious predators such as the velociraptor were most active by day.

Researchers now think that, as in Steven Spielberg movie Jurassic Park, meat-eating dinosaurs hunted at night.

It used to be thought that early mammals in the dinosaur era found refuge in the night, when the reptilian killers were not around.

But a study by US researchers of eye sockets in the fossil skulls of dinosaurs, an accurate way of determining day/night activity, suggests this was not the case.
